Your friend, particularly someone from the same area of the city as you. Origin is from New Orleans term "ward", how the city is divided.
It began as "wassup 7th waaaar-day", "wassup 9th war-daaaay" and the sound evolved to "whoadie". Eventually people dropped the ward number and started saying "wardy" and "whoadie."
(wo' - day) slang; A term originating in New Orleans. In most cases where the word "dude" "bro" or "homie" would be used, whoadi can be substituted. Has often been incorrectly spelled "wootay" "woadi" "wotay" and "whodi." It is not uncommon for New Orleans natives to shorten the term to just "wo."
